Command & Conquer (abbreviated as C&C or CnC) is a real-time strategy franchise created by Louis Castle and Brett Sperry in 1995. The games are divided to the universes to which they belong to: Tiberium Universe, Red Alert Universe, and Generals Universe. The Generals universe is not connected to the other two, while the first Red Alert was originally intended as a prequel to the Tiberium saga, and is hence arguably considered a part of both. The first game, Command & Conquer, was based on Westwood's Dune II: Building of a Dynasty from 1992.
